`Application led July 28, 1820. Serial No. 3912520,

looll whom it may concern:

Be it knovnfthet l ALBERT P. LEE, a citi/en of the United States,residing1 at Chicago, in' the county of Cook and State of, Illinois,have invented a certain new and useful Improvement in Rail Constructionfor Rolling'lloppers, of which the followingl is a full,4 'lear,concise, and exact description, reference being had to the accomforminga. part of this specification.

` This invention relates to rolling hoppers and more particularly to theconstruction of th i rails upon which the hoppers are adapted to roll. 4

In providing` a. dumping' hopper for vehicles in which the hopper isadapted to roll automatically from a load carrying position to a dumpingposition and to complete the dum-ping;A action `by a pivotal movementabout a'point at or near the end of the rail,` it hasbeen found thatsome means must be provided to prevent the hopper from becomingdisengaged at its pivots, while the pivotal movement is going on. It isa purpose of this invention to provide a rail of the above characterwith means to effectively prevent the disengagement of the hopper fromits pivots.

More particularly it is the purpose of this invention to provide a railhaving portions extending downwardly from the center thereof, andprovided with pivot means at the ends thereof, with means to prevent thedisengagement of the hopper from said pivot means while the hopper ispivoting thereon.

It is a further object of the invention to provide a vehicle carrying ahopper having pivot pins thereon, with rails upon which said hopper mayroll, having' socket members at its ends in which said hopper may pivoton said pins that are provide-.d with guards to prevent the pins fromleavlng the sockets while the hopper is in such position that it issupported entirely by said pins and sockets, and thus prevent the hopperfrom tilting olf the ends of the rails to the ground. Y

Other objects and advantages of the invention will appear as thedescription of the accompanying drawings proceeds, in which likecharacters of reference are used to designate like parts, and in whichFigure is an end view of a rolling hop- Pel, Shen/.111s .011.6 ,Of therails associated therewith inside elevation, i `l Fig. 2 is a. topV planview of one of the rail ends. Referring in detail to the` drawings, theinventiony comprises the hopper 3 having the bearingrail 4 thereon witha curved portion l5 adapted to, cooperate with the rail '6 mounted onthe vehicle framework 7 in any suitable manner. The hopper 3 is providedwith pivot pins 8 where the curved portions 5 of the bearing rail meetthe straight portions thereof-` i In F ig. 1 the hopper` 3 isk shown inits central load carrying` position and thisihopper is held in thisposition by suitable retaining devices (not shown), and when these are.released it is adapted ,to roll automatically from the centra-l portion9 of the rail 6in either direction down the inclinedportions 10 thereofand the curved hearing rail portion 5 of the hopper and the inclinedportions 10 of the rail 6 are so proportioned that when the hopper hasro-lled to the end of the curved portion of the bearing rail pins 8 willengage in their respective hookshaped members 11 which are secured tothe end portions of the rail 6 and the hopper will pivot on said pins 8in the sockets 12 formed in the hooked brackets 11 and complete thedumping operation of the hopper.

As shown in F ig. 2, the brackets 11 are bifurcated and have a portion13 extending on each side of the web portion of the rail 6, the railbeing;` in the form of an I-loeam and these bifurcated portions 13 aresecured to the web in any rivets 14. It will be seen on referring to Fig. 1 that the bracket 11 is rigidly secured. to the rail 6 by means ofthe rivets 111 as the edge portions of the bifurcated portions 13 engagethe flanges of the Lbeam both at the top and bottom thereof thus forminga -very strong and rigid structure.

suitable manner as byV the upper webs of the rails 6 have been extendedas shown'at 16 to partially close the member 16 and between the member16 Y and thev rear wall of the socket referred to by the numeral 17 inFig. 1, thus preventing theV disengagement of the pin and socket Vwhilethe pivotal movement is going on or 4after the hopper has reached itsfinal dumping position.4

Upon referring to Figs. l and 2 it will ber seen that the hook-shapedbracket 11can be reinforced in an 1 suitable manner as by the .web 18.From the foregoing description it will be seen that a rail for rollinghoppers is providedthat has socket members mount ed on the ends thereofabout which the hopper Vmay pivot and which socket members are Vprovided`with guards to prevent the disengagement ofthe Vpivot pins carried bythe hopper from the sockets.

`Having thus described my invention I desire to have it understood thatldo not intend to .limit myself'to the exactV details ofconstructionshown 1n the accompanying drawings or described in the foregoing Y.

specification -except as defined by the following claims:

1. In a device of the character described, the combination of a rail, ahopper adapted to roll on said rail from charge carrying to dischargeposition, coperating pivot members on said rail and hopper comprising apin and a socket portion in which said pin is adapted to pivot, and an"overhanging guard to hold said pin in said socket when said hopperreaches its limiting dumping position. K

2. In a device of the character described, a rail having a socket membersecured tothe end portion thereof, and an extension on said railextending partially over the mouth of said socket to Vact as a guardforl the same.

3.111' a device of the character described, a rail having a socketmember secured to the end portion thereof, means adapted to venter saidsocket and -pivot therein, and a finger extending partially over themouth of said socket to provide a constricted entrance opening to saidsocket, said opening being positioned out of the normal path of movementof said means in said socket memberV as the pivoting movement iscompleted.

In witness whereof, I` hereunto subscribe my name this 16th day of July,A. D. 1920.

ALBERT P. LEE.
